Chris Brown -- My Lawyer's a STUD -- He Deserves a Lamborghini

Ya might see Mark Geragos driving around town in a bright orange Lamborghini in the near future ... 'cause Chris Brown says it's the LEAST he could do for his super-lawyer for saving his ass ... again.

Brown hit the club scene in Hollywood last night after Geragos worked his magic and obliterated the hit-and-run case against the singer ... a huge deal considering Brown was facing jail time if convicted.

But outside Hooray Henry's, Brown told TMZ he's eternally grateful for his attorney ... and to show his gratitude, he's considering giving the guy an UNBELIEVABLE thank you gift ... the kind of gift that goes 0 to 60 in 2.9 seconds.
